Follow-up techniques in a large-scale test validation study

Abstract

Records were kept on success of techniques used to obtain follow-up information on occupational and educational status of 12,615 individuals 2 yrs. after being tested in Grade 12. Various techniques were used, with varying degrees of success. The information was obtained for most individuals through use of letters, an effective and low-cost technique for obtaining factual information. It was found to be worthwhile to send as many as 3 letters, if necessary, before trying another technique. Among the most successful techniques, in terms of percentages of attempts that were successful, were telephone calls, presonal visits, employment service records, and knowledge of individuals in the community.
